The new EPA rules for auto emission standards were setup under the Obama administration in 2012. The rules are a major part of the effort to meet the challenge of pollution and clean air. The Trump administration and EPA chief Scott Pruitt plan to reverse the higher standards. The new standards which had the support of automakers when enacted require that average fuel economy be doubled to about 54.5 miles per gallon by 2025. This would cut oil use by 12 billion barrels over the lifetime of the cars and reduce carbon dioxide pollution by about 6 billion tons. 

The EPA under president Trump does not say how much the standards will be rolled back. This also leads to one more tension between California and the Trump administration. California plans to vigorously oppose the rollback. Under the Clean Air Act of 1970 California has historically made its own rules and was followed by 12 other states making up one third of the car market in the U.S. If the Trump administration is able to to this it would create two markets for automobiles in the U.S. which is not in the interest of automakers who are having second thoughts about the change.

Amazingly a suburban Virginia Chevy dealership has vigorously opposed being used as the location for the EPA under the Trump administration making an announcement on this issue. Chevy dealerships are saying the Trump administration does not have the facts, that the auto industry has done very well in the last 4-5 years. Chevrolet and GM do not want to be associated with the politics on this issue.

California has historically acted as a pioneer in automobile standards with the rest of the nation following. The Trump administration move would be an effort to break this precedent.
